Aug 10 2017 In Fig. 5b similar to CBM first a downward trend at a rate faster than tests 1 to 3 followed by an upward trend with a slower rate of tests 3 and 4 is observed for circularity due to the grinding of coarse-grained particles. This rapid rate indicated the reduction in strong abrasion effect on circularity resulting from direct collision between ball and particle while the abrasion mechanism from initial impact of the ball

What Is A Low Loss Header Hamworthy Heating

Hydraulic separation of primary and separately pumped secondary circuit via a low loss header is recommended to avoid this. How does a low loss header work By separating the two systems it allows boilers to operate at a constant flow rate in the primary circuit whilst flow rates and temperatures may vary in the secondary circuit.

Corrosion Behaviour Of Type 316L Stainless Steel In Hot

Corrosion Behaviour Of Type 316L Stainless Steel In Hot

Oct 20 2019 The corrosion behaviour of type 316L stainless steel in aqueous 30–50 wt. NaOH at temperatures up to 90 C has been elucidated. Exposure to room temperature environment showed parabolic weight loss behaviour with corrosion rates of up to 0.4 mmyear. Higher NaOH concentrations and exposure temperatures resulted in a reduced stability of the electrochemical passivity domain

Pressure Loss From Fittings Equivalent Length Method

Pressure Loss From Fittings Equivalent Length Method

Fittings such as elbows tees and valves represent a significant component of the pressure loss in most pipe systems. This article details the calculation of pressure losses through pipe fittings and some minor equipment using the equivalent length method. The strength of the equivalent length method is that it is very simple to calculate. The weakness of the equivalent length method is that .
